To all whom it may-concern:

Be it known that I, JOSEPH W. WALDORF, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Im rovement in Motor-Vehicles, of which the i lowing is a full, clear, and exact descriptiomsuch as will enable others skilled in the. art to which it appertains to maize and use the 831150, referentce being had tot eaccom and raw orming part of this spec'tiizatioii, in wh i h Figure 1 is a top plan view of the underframe of a vehicle provided with'a driving gear and a steering gear constructed in accordance with my invention; Figs 2 isa vergical seci ional view takffrgpd the line 12-172 of ig. 1n ig. 3 is an en vertica o tudinal sectional view taken through file center of the drive'shaft; Fig.4 is an enlarg ed sectional .view taken on the line 4-4 of ig. 1; and Fig'. 5 is an. enlargeddetail view showing the con truction of one of the internal gearsthat are carried bytherear wheels.

25 This invention relates to motorvehicles mg gearwhichcanfbe applied to n ordinary horsepropelled vel iic.le' tofconvert, itinto a motor-driven vehicle; I J

Brieflyff describedp my improved drivin gear consistscof. a driving shaft provide with al-plura ityxofpinions which are adapted to coiiperate with ears connected to the rear of the. ve icle, a driving sprocket wheellinounted' onIsaid shaft; and means actuated by the front axle of the vehicle for disconneetmgoneof said pinions fronrsaid drivings rocket wheel when the front axle of the ve 'clc turns, thereby providing a differential or, compensating gear which permitsthe rear wheels of the vehicle to travel at different rates of speed.

Refcrringgto the drawings which illustrate the preferred form of. my invention, 1 designates the frontaxle of a vehicle": tltsl 'lnltes A the reach bars of the umlerl'rume, and It the rear axle onwhich the rear tatably mounted. a a

The steering mechanism comprises a segmentul sha xulhar 5 secured to the front axle 1 and rovided-witli*internnl gear teeth '6 thattmesli with a bevele'ttpinion 7 on the lower end of an inclined steering shaft 8. A plate 9 is secured to the reach bars 2 to form wheels 4 are roand has'for. its objec t'to provide a novel and. slmpla' fox-moi 'drivinggear and also-a steer,-

drive shaft on with internal gears 13 secured to the inner sides of the rearwheels 4. Said drive is composed of two sections 14 and 15 which Is provided at'its inner end with a-diskshaped head 16, as shown in butting against each other an being mount ed insideof the hub of 'a sprocket wheel" which receives the dri chain 17'.

hub 'of the sprocket Wm 17 is formed by two flanged s eeves.l8which are sec b fastening devices 19 to the sprockem and the vertical flanges of said sleeve! are separated, as shown in Fig. 3, to form a housindependentl of each other but reventing suidscctions in moving lon 'tuiiallyrslative"ly to'eachother. Thehu t wheel l7..is' loosely mounted *on the drive I .shaft and is (pro'videdwith two setaof-elutch" teeth 20 "an 21 that cooperate with clutch members 22 and 23 which are splinedto the each side of the 'hub of the sprocket wheel. When both sets of clutch teeth on the hub of the sprocket wheel min engagement with the clutch membeiiZ and 23 rotary movement will be impartedto sections of the driveshaft and conse both of the rear wheels'of the'vehicle; positively driven at the se. na speed by I of the pinions on the drive shaft that'rnesh with the internal gears on the rear wheels.

th qtle tlg mabearing for the lower end of the Themg for the heads 16 on the ends of the drive shaft sections, thereby permittin the two so "sections 14 and 15 of the drive s t to rotate To permit the vehicle to turn properly it is necessary for'the inside rear wheel to travel slower than the outside rear wheel and to this end I have provided means for automaticall d isconnecting the drive pinion for the insi a rear wheel from the driving sprochetl7. 1 accomplish this preferably by means of pivotnllytnuuuted cams 24 and 25 which engage and mot-e the clutch members 22 and'23, respectively, out of engagement withthe clutch teel h on ,the hub of the s rocket wheel 17, said cmns being controlled by rods 26nd 27,

rcsicctivelv, that are secured to the front cle axle l. hen the vehicle is turnfll to lilo. right the rod 27 will be pulled forwardly and thus move the cam '25 rcnl'wnrdlt' tn cimsc it so as to enable an engine to be used for propelling the vehicle. I prefer to provide the rear heels with internal gears, as herein shown. but it will. of course. he understood to en the beveled collar 23" on the clutch that external gears could he used without demcm m! 23, thereby moving said clutch parting from my invention. Furthermore, l member out of engag ment with the teeth .2! wish it to be nndcrstoml that my invention is on the hub of the sprocket wheclsous to disi not limited to cums for moving the clutch c nn t the section of the drive shaft from members out of engagement with the huh of M10 riving sprocket 17. The rod 26 which the driving sprocket as various other devices controls the cam 24 will nlso be moved when the vehicle turns to the right but said cnm will be moved forwnrdlv so that it does not engage the beveled collar on the clutch member 22, said clutch member remaining in engagement with the clutch teeth on the huh "of the a )rocket whcelso that the outside rcar whccl'o the vehicle. will be positively driven. When the front axle resnnies its former posiaprin 23'', which is inte mem r and a shaft. bearing 280a the reach bar, will move said member 23back into eneman't with the hub'of the sprocket wheel.

' Vhen the vehicle turns to the left the cam tion, the cam 25'will carried out of engagc- ;'loosel v mounted on said ment with the clutch member 23 and a coiled I with clutch members. clutch members splined osod between and l to the sections of the drive shaft and cocould he used for this purpose.

Having thus described my invention, what 1 claim as new and desire tosec nre by Letters Patent is: l I, A drivim gear for vehicles, comprising gears adaptor to be connected to the. rear wheels of a vehicle, a drive shaft formed in sections, pinidns secured to said sections and meshing with said gears. a drive sprocket shaft and provided operating with those on the drive sprocket for connecting the sections of the 'drive shaft to said sprocket,v and automatic means for disconnecting either section of the drive 24 will engage the clutch member .22 so as to, shaft from said drive sprocket; substantially disengage the section 14 of tho'drive shaft-Q as described.

from the sprocket wheel 17. 'lhe drive shaft- A 18 mounted in the bearings 28 on the reach bars and also in bearings 29 carried by the.

the bearings 29 are also hdjustable. Each of said bearings 29, as'shown c "arly in Fig. 4', is rovided with a rearwardly extending hollow 'shank-ZQthattits over a rod 30 aving a dc:- nding portion which is adjusts. ly mounted in a tubular bearing 31 carried by the rear.

axle The depending portion of the rod 30 is, secured in tho bearing 31 by set screws 31 so" that the rod can be adjusted vertically, and the hollow shank 29 of the bearing 29'is sett'xcured to the rod 30 by set screws 2}) so that "the bearings 29 can be adjusted horizontally.

filrethia way-I am able to adi'ust the bearings 29, for. the drive shaft blot '-vertically and horizontnlly'so as to-caustlic pinl'ons 1;! to
